i have two questions and a bug notification for version 1.10

i am trying to use a flex and bison parser to read several files in succession,
and finding a problem with the state in which the parser is left after the
first file is read

on the second file, i get a message
	unexpected token "" at line 1
(i initialize yylineno before each parse,
and the input file is closed after each parse)

so, my two questions are:
	is this the right forum for questions of this type?
	how can i get the parser to read a real token
		instead of remembering an old one
		(which is what i think is going on)?

separately,
there appears to be a bug in the implementation of the "-t" flag -
the generated C file has a line
#define YYDEBUG
but all the tests of YYDEBUG are of the form
#if YYDEBUG != 0
which gets a "parse error" from the GNU C compiler

either the definition should say
#define YYDEBUG 1
or the tests should read
#ifdef YYDEBUG
(the former is the better solution)

when i explicitly compile the generated file with -DDYYDEBUG,
it works as i expected it to

thanx much for any help

more later,
